release, but they trigger subtle timing dependent kernel bugs
in older OSF/1 releases.

up the includes ourselves.
Add missing return statements after finding an "add imm{16,32},sp"
instruction.

the current processor
here. Call gdb_target_exec before rebooting the target, to make
sure the connection to the target is closed.
(gdb_load): Pass the name of the executable to gdb_target_monitor.
Don't call gdb_file_cmd here; let gdb_target_monitor do it.
